How to do FFT spectral analysis

雷达中频回波仿真，对脉内起伏进行仿真，含脉内慢起伏和脉内快起伏(Radar IF echo simulation, simulation intrapulse downs, including slow downs and pulse-pulse fluctuations within the fast)

this code has been for modulating the signal in the matlab ,this is very precise and usefull

说明：  电力系统无功优化相关，基于粒子群优化算法的电力系统无功优化设计(Power system reactive power optimization)

matlab编写的扫雷的仿真游戏 可实现基本的游戏功能 对初学MATLAN者来说是一个不错的练手小例程(matlab simulation game written in de-mining can realize the basic set of gaming features for beginners MATLAN who is a nice little routine practice hand)

QPSK调制解调技术在瑞利信道中的研究分析。(QPSK modulation and demodulation in Rayleigh Channel analysis.)

The radially averaged power spectrum (RAPS) is the direction-independent mean spectrum, i.e. the average of all possible directional power spectra. This function computes and plots the RAPS of an input image. The function was written to produce the RAPS for square weather radar reflectivity images so you will have to relabel the plot axes and title to suit your needs. The radially averaged power spectrum provides a convenient means to view and compare information contained in 2D spectra in 1D

程序给出了0~10发音的语谱图，其中采用分帧函数对信号进行分帧处理然后在用fft算法得到频谱信息，后用灰度图像表示(Program gives the pronunciation of words from 0 to 10 spectra, which employs the signal sub-frame function and then in the sub-frame processing spectral information obtained with the fft algorithm, then said with a gray image)

采用汉明码的BPSK仿真程序，译码使用硬判决，仿真给出误码率曲线(BPSK simulation procedures, the use of hard-decision decoding, given BER simulation curve)
